    P1000 fault won’t reset.

    Hi all,
    Just when I thought things were looking up, my rarely driven D2 with a recently installed 4.6 L motor from an old RR has started running a little rough.
    Because of this I searched for faults on the Nanocom and found this one:

    P1000 CAMSHAFT SENSOR FAULT/VALVE TIMING ERROR DRIVE CYCLE A
    OCCURRED 1 TIMES
    SIGNAL INVALID
    FAULT IS CURRENTLY PRESENT
    FAULT DETERMINED AS PERSISTENT
    FAULT DOES NOT CAUSE THE MIL LAMP ACTIVATION

    The fuel consumption also seems to be worse (something I didn’t think was possible).
    Even with the motor off, the Nanocom doesn’t seem to want to reset the fault.
    Any thoughts will be greatly appreciated.

    Does the RR motor have a camshaft sensor?

    The Thor motors have a camshaft sensor to enable start within 1 revolution of rotation as the flywheel sensor only triggers once per revolution.
    The Thor ECU will be looking for a camshaft sensor signal to correctly position the firing order .

    From memory mine had the timing cover changed over from my old Thor 4.0 when I went RR 4.6 into the D2.

    Thanks for your replies.
    The timing cover, sump and sensor assembly were all swapped over. The motor had ran perfectly up until now.
    I believe the motor will not start at all if the crank position sensor (the one that looks at the flywheel) is faulty, so it must be okay.
    Philip, are you implying that the sensor on the front of the motor might be the cause?

    If you have a camshaft sensor , yes.

    Thats funny,, I have always been happy with my fuel consumption,,
    and I doubt theres much between the two..


    I've never had a camshaft sensor error.. and I was of the opion the BSL had broken everything... and as you would know biggin, its not a common Thor fault at all

    Your right Pedro I don’t think I’ve ever read of anyone having problems with it.
    I actually read that very page this morning.
    You have misunderstood my bad economy comment. It’s only started to happen in the last couple of days. I’ve had the 4.6 for over a year now and I agree that the difference between it and the 4.0 has been negligible, until now.
    After checking it over with the Nanocom, I suspect it’s not a sensor problem at all, although I plan to check it with a frequency meter. The only bad readings I could find was No6 cylinder misfiring, so possibly a coil pack. Hope not, because it’s a mongrel to change.

    The latest trick I heard was to drop an engine mount...

    Before I muck around with the coil pack, I might try disconnecting the front crankshaft sensor and see what happens. If no change, it could be a wiring problem. It would explain why I can’t reset the error. Anyone else had this P1000 fault?

    IMO you should double check with other tester too cos that P1000 CAMSHAFT SENSOR FAULT/VALVE TIMING ERROR is very suspect as the CMP fault codes are from P0340 to P0349 while P1000 = "ECM memory erased - no codes stored"
